Or as long as we're speculating: Back in the Napoleonic era, when everyone in Naples was fighting the English, along comes an English general named Clodes, and he is defeated (vinto), and suddenly the jubilant men are all naming their sons Clodesvinto. It's far-fetched, probably ridiculous. Let's hope someone from Molfetta chimes in with the real story behind the name. Good luck, Mauro.
